    - 4.0.0 Firmware & 01.59.00 Baseband Click me
    - 4.0.1 Firmware & 01.59.00 Baseband Click me
    - 4.0.2 Firmware & 01.59.00 Baseband Click me
    - 4.1.0 Firmware & 02.10.04 Baseband Click me
    - 4.2.1 Firmware & 03.10.01 Baseband Click Me
    - 4.3.0 Firmware & 04.10.01 Baseband Click Me
    - 4.3.1 Firmware & 04.10.01 Baseband Click Me

    I wanted to completely erase my iphone and sell it but if i do it via itunes, it will upgrade it to iOS 4.3.3. I want to keep 4.2.1 so is it possible to save the 4.2.1 firmware and restore using that. That way, i will still have my 4.2.1. Also, can i just restore to the 4.0.0 fireware & 01.59.00 baseband, this will allow me to unlock the iphone without gevey sim.
